• Operating Frequency: Suitable for a wide range of applications, typically in the audio and low-frequency ranges.
• Package Type: Commonly available in TO-92 and other similar packages.

Electrical Specifications:

• Collector-Base Voltage (Vcb): 50V
• Emitter-Base Voltage (Veb): 5V
• Operating Junction Temperature (Tj): Up to 150°C
• Thermal Resistance (Junction to Ambient, RθJA): Typically around 200-250 °C/W, depending on the specific package.

Applications:

• Audio Amplifiers: Ideal for use in low-frequency audio amplification circuits due to its linearity and performance.
• Switching Applications: Suitable for low-current switching applications, such as driving small relays and LEDs.
• Signal Processing: Works effectively in analog signal processing applications, including mixers and filters.
• General Purpose: A reliable option for a variety of general-purpose applications requiring NPN transistor functionality.

Important Notes:

• Polarity: Ensure proper connections; as an NPN transistor, the collector must be at a higher potential than the emitter for the transistor to conduct.
• Biasing: Proper biasing is crucial for ensuring that the transistor operates in the desired region (cut-off, active, or saturation).
• Heat Management: Consider thermal management strategies, such as heat sinks or airflow, when operating near maximum ratings.
